Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data communication device, and more particularly to a data communication device such as a personal computer or a word processor having a data communication function.

[Prior art] Today, word processors having a data communication function are:
Along with personal computers, it is becoming widespread as a terminal for personal computer communication. Recently, some documents that can be transcoded from a word processor and sent to a G3 facsimile have appeared. In addition, it is possible to easily send (broadcast) a document from a plurality of devices to a plurality of destinations.

[Problems to be Solved by the Invention] However, conventionally, even if there is a change in the document information after transmission, the document information after the change cannot be delivered to the destination unless the transmission operation is performed again. In addition, if the document is a change in the notice of holding a conference, if the retransmission is forgotten, it will cause a great deal of trouble to the other party, and the resetting of the destination at the time of retransmission requires a great deal of effort.

An object of the present invention is to eliminate the above-mentioned drawbacks of the prior art, and an object of the present invention is to provide a data communication device that ensures that changed information reaches a destination.

Means and Action for Solving the Problems In order to achieve the above object, a data communication apparatus according to the present invention has a transmitting unit for transmitting information, and a first storage unit for storing information transmitted by the transmitting unit. A second storage unit for storing the information of the transmitted destination; a detection unit for detecting that a change has been made to the information of the first storage unit; and a fact that the detection unit has been changed. The transmission control means for controlling the transmission means to transmit the changed information in the first storage means in accordance with the destination information in the second storage means by detecting the This is an overview.

As a result, the presence of a change to the transmitted information is automatically recognized, and the information is reliably retransmitted to the transmitted destination.

[Description of Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram of the word processor of the embodiment. In the figure, reference numeral 10 denotes a CPU, which performs main control and processing of the word processor. Reference numeral 11 denotes a ROM which stores, for example, the control programs shown in FIGS. 3 and 4 to be executed by the CPU 10. Reference numeral 12 denotes RAM, which the CPU 10 uses as a work area. 4 is a CRT for displaying document information, etc. 5 is a keyboard (KBD) for creating, editing and inputting document information,
Reference numeral 6 denotes a flexible disk drive (FD) for inputting document information and information on whether or not the document information is transmitted.
D) and 7 are printers (PRN) for recording document information, 8 is a communication control unit (CCU) for communicating with another word processor or the like, and 9 is a telephone line.

FIG. 2 is a diagram for explaining an information table on the presence or absence of transmission according to the embodiment. In the figure, reference numeral 1 denotes a document registration list, which stores an indicator D1 of transmitted document data and a pointer 3 indicating a destination list to which the document data has been transmitted. A transmission destination list 2 stores addresses (or indicators) A, B, and C of destinations to which the document data has been transmitted.
Here, when the pointer 3 points to the transmission destination list 2, it indicates that the document data D1 has been transmitted to the destinations A, B, and C. When nothing is written to the pointer 3, it indicates that the document data D1 has not been transmitted anywhere.

Such an information table is written on a disk together with the document data, and when the document data is read, the information table is also read.

FIG. 3 is a flowchart of the first transmission process of document data. In the figure, in step S1, the document data and the information table are read into the RAM 12 via the FDD 6. Preferably, the contents of the information table are displayed on the CRT 4 together with the document data. In this case, since this document data has not been transmitted anywhere, the pointer 3 of the corresponding information table is not transmitted.
And the contents of the transmission destination list 2 are blank. Step S2
Then, a destination is input to the transmission destination list 2 from the keyboard 5. Further, when a transmission key (not shown) is pressed, the process proceeds to step S3, and the document data is transmitted to the specified destination. When the transmission to the designated destination is completed, information indicating the transmission destination list 2 is written to the corresponding pointer 3.

FIG. 4 is a flowchart of the document data retransmission process. In the figure, in step S11, the document data and the information table are read into the RAM 12 via the FDD 6. Step S
At 12, the document data is corrected by the keyboard 5. After the correction is completed, if a write key (not shown) is pressed, the flow advances to step S13 to rewrite the corrected document data on the disk. At this time, the corrected document data in the RAM 12 and the uncorrected document data read from the disk are matched in character units, and the presence or absence of a mismatch is detected. In step S14, it is determined whether or not there is a correction. Step if correction
In step S15, the pointer 3 in the information table is checked to determine whether the document data has been transmitted in the past. If the pointer information is set in the pointer 3, it indicates that the information has been transmitted once in the past.
Proceeds to S16, the transmission destination list 2 indicated by the pointer information
Then, the corrected document information is transmitted to the corresponding destination according to the destination information. If the determination in step S14 or S15 is NO, the process exits without retransmission.

In the above-described embodiment, when the document data is modified, the document data is retransmitted unconditionally, but the present invention is not limited to this. For example, a step of asking the operator whether retransmission is necessary may be provided.

In the above embodiment, the word processor is used. However, the present invention is not limited to this. Any other devices such as a personal computer and other devices for performing data communication may be used.

[Effects of the Invention] As described above, according to the present invention, when the transmitted information is corrected, automatic retransmission is performed, so that the latest information always arrives reliably.
